Rear washerfluid leaking into boot Ibiza -13

[Klimaxx]

Got a problem with washerfluid leaking into the back of the car from the fluid connector on the rear wipermotor, seems to be coming from two holes on the sides of the connector troed to clean the washer nozzle and the connector just incase something is stuck with a needle but it didnt help at all… the holes look like they are supposed to be there. Been thinking about sealing them with silicone but im worried that its maybe leaking because something in the motor is clogged and will make something else leak if i seal the holes. Holes are marked with red on the connector
